Frequently asked questions

The outdoor unit is installed at the entrance and has the camera, call button and speaker. The indoor monitor is the screen inside the home or office where you see the visitor, talk to them and unlock the door.

Yes. Vallabh Enterprises is the authorized pan-India distributor for DNAKE video door phones.

Yes. Societies typically combine a lobby panel at the gate or building entrance, indoor monitors in each flat and a guard station at the security cabin, all connected over the building network.

The main types are dome cameras (ceiling-mounted, discreet, vandal resistant), bullet cameras (visible, long-range, ideal outdoors) and eyeball or turret cameras (compact with strong night vision). Most current installations use IP cameras recorded on an NVR.

Yes. IP CCTV systems can be configured for remote viewing so you can watch live and recorded video from anywhere using a smartphone, tablet or laptop connected to the internet.

An NVR (Network Video Recorder) records video from IP cameras over the network and stores it on hard disks. NVRs are sized by channels — for example 8, 16, 32 or 64 cameras.

Yes. Vallabh Enterprises installs CCTV systems at residential and commercial premises, from a few cameras at a home to large commercial sites.

A reader at the door reads a fingerprint or card and sends it to a controller. The controller checks whether that person has permission for that door at that time, releases the electric lock if they do, and logs the entry.

Biometric access control identifies people by a physical trait — most commonly a fingerprint — instead of, or in addition to, a card or PIN. It prevents credential sharing because a fingerprint cannot be handed to someone else.

Yes. The range includes boom barriers, car-park barriers, pre-security gates and accessories such as loop detectors, photocells and UHF card readers.

Yes. Vallabh Enterprises supplies, installs and maintains both conventional and addressable fire detection and alarm systems, including control panels, smoke and heat detectors, manual call points, hooters and response indicators.

A conventional system reports alarms by zone, which suits smaller buildings. An addressable system gives each device its own address and shows exactly which detector or call point triggered the alarm, which suits larger buildings.

Yes. Fire alarm panels run on mains power with a standby battery that is kept charged, so they continue to work during a power failure.

It is a burglar alarm system that uses motion detectors, door and window sensors and a control panel to detect unauthorised entry and raise an alarm when the premises are armed.

A PIR (passive infrared) detector senses the body heat of a person moving through its field of view and signals the alarm panel. Ceiling-mounted and curtain-lens versions cover different room layouts.

Yes. Wireless detectors, magnetic sensors and keypads connect to the control panel by radio, which makes them suitable for existing homes and offices.

Both card-based and biometric (fingerprint) time attendance systems are available, along with centralized time-attendance software for organisations with multiple locations.

Many terminals support both functions, so the same device can record attendance and act as an access control reader for that door.

An EPABX is a traditional in-house telephone exchange using analog or digital phones. An IP-PBX provides the same features over a data network using VoIP and adds capabilities such as video calls, conferencing and mobile apps.

Yes. FXO gateways connect existing analog phone lines to an IP-PBX.

A PA system typically has a call station or microphone, an amplifier (or all-in-one amplifier), a controller for zones, and ceiling or box speakers installed in each area.

Yes. Zone call stations let you page selected zones — such as a single floor — instead of the whole building.
